Density ? in the atmosphere cannot be measure directly, but can be calculated from pressure and temperature measurements using the Ideal Gas Law ?=p/RT where R is the specific gas constant for air, p is pressure and T is absolute temperature. The Kestrel 3000 hand held instrument shown in class gives accuracy estimates of 1C for temperature and 1.5 mb for pressure. Based on these accuracy estimates, what would be the uncertainty in the density measurements for measurements made with the instrument at a temperature of about 20 C and a pressure of 1000 mb.
